Q: Ama-Ceramic capacitor athintwa yizigigaba zokuguga
Ama-Ceramic capacitors athintwa yizigigaba zokuguga ezihambisana nezinguquko kwisakhiwo se-dielectric crystal, esizibonakalisa njengezinguquko ku-capacitance kanye nesici sokuqothula ngemuva kokudubula kokuqala kwezinto ze-dielectric.Ngokuvumelana namamodeli amisiwe, izinto zokwakha ze-Dielectric ze-EIA Class I zithinteka kancane futhi ziqashelwa kabanzi njengezingagugi, kuyilapho izinto ezisebenza ngogesi ze-EIA Class II zithinteka ngokusesilinganisweni futhi izinto ze-EIA Class III zivame ukuthinteka kakhulu.Le nqubo yokuguga ingasethwa kabusha (noma idivayisi “de-aging”) ngokuchayeka emazingeni okushisa angaphezu kwe-Dielectric’s Curie lokushisa isikhathi eside ngokwanele ukuvumela ukwakheka kwekristalu ukuthi sakhe kabusha;izinga lokushisa liphakeme, isikhathi esidingekayo siba sifushane.Njengoba izinga lokushisa le-Curie lama-dielectrics amaningi e-ceramic liphansi kunalelo okuhlangatshezwana nalo ezinqubweni eziningi zokuhlanganisa, kungenzeka ukuthi idivayisi izoba mdala okungenani kancane phakathi nokuhlanganisa.
Lokhu kuziphatha kokuguga kwengxenye kuvame ukuvezwa njengephesenti lokushintsha kwamandla eshumi leminyaka lamahora, uma kuqhathaniswa namandla alinganiswa “ekushiseni kokugcina,” ngesikhathi sokugcina ingxenye ishiselwa ngaphezu kwezinga lokushisa le-Curie isikhathi eside ngokwanele ukuze iguqule ngokuphelele ikristalu yayo. isakhiwo.Ngamanye amazwi, i-capacitor enezinga lokuguga elingu-(-)5%, likalwa ku-100uF esimweni “sehhavini elisha”, izolindeleka ukuthi ilinganise cishe u-95,90 no-85uF ngemva kwamahora angu-1, 10 kanye nayi-100 iphuma kuhhavini. , ngokulandelana.
Ngokusobala, lokhu kuphakamisa umbuzo wokuthi i-capacitance ebizwa ngokuthi ingxenye kufanele ibe yini, futhi uma leyo mali ishintsha njalo, ingxenye izosetshenziswa eshalofini ngisho noma ingazange isetshenziswe ekufakweni kwayo kwasekuqaleni.Izindinganiso zemboni i-EIA-521 kanye ne-IEC-384-9 zibhekana nalolu daba, ngokuyisisekelo zithi ingxenye kufanele ifinyelele inani layo elishiwo lokubekezelela amahora angu-1000 (cishe izinsuku ezingu-42) ngemva kokushisisa kokugcina.Imaki yeminyaka eyishumi elandelayo (amahora angu-10K kanye nangu-100K) ihumusha esikhathini esingaphezudlwana konyaka ongu-1 kanye nangaphezulu kancane kweminyaka eyi-11 ngokulandelana.Ukuqhubeka nokwenza izinto zibe nzima, inqubo yokuguga yenzeka ngezinga elincike kumazinga okushisa;kufika kuzinga lokushisa le-Curie le-dielectric, ukwenyuka kwezinga lokushisa ledivayisi ngokuvamile kusheshisa inqubo yokuguga.
Njengoba izenzakalo zokuguga zingabangela amadivayisi ukuba abonakale ngaphandle kokubekezelela kwawo okucacisiwe, abaklami bemikhiqizo nabahloli bokukhiqiza kufanele baqaphele leli qiniso;ukuhlolwa kwezingxenye ezisanda kugcwaliswa kabusha kufanele kulindelwe amanani aphezulu kancane, futhi idizayini kufanele ibe nemajini eyanele ukuze ivumelane nokusebenza okuvamile kwedivayisi njengoba ikhula.Amasekhethi okuguqula amandla ayisibonelo esihle salapho lo mphumela ungaba khona ingozi enkulu, njengoba ama-capacitor e-ceramic ngokuvamile agcina ethinta kakhulu amaluphu okulawula amasekhethi anjalo, njengezingxenye zenethiwekhi yesinxephezelo noma njengezihlungi.Amasistimu abonakala ezinzile ngaphansi kwethonya lokuguga kwe-capacitor ngesikhathi somhlangano angase angazinzi ngokuhamba kwesikhathi, njengoba ukulahlekelwa amandla ngenxa yokuguga kuthinta amandla e-loop yokulawula.Okubaluleke kakhulu, uma amanani azinzile we-capacitance ngokuhamba kwesikhathi ebalulekile, gwema ukusebenzisa ama-capacitor amadala.
I-Zhejiang NeoDen Technology Co., LTD., eyasungulwa ngo-2010, sisesimweni esihle sokungagcini nje ngokukunikeza umshini we-pnp osezingeni eliphezulu, kodwa futhi nenkonzo enhle kakhulu yangemva kokuthengisa.Onjiniyela abaqeqeshwe kahle bazokunikeza noma yikuphi ukwesekwa kwezobuchwepheshe.
Ithimba lesevisi yonjiniyela abayi-10 elinamandla ngemva kokuthengisa lingaphendula imibuzo yamakhasimende kanye nemibuzo phakathi namahora angu-8.
Izixazululo zobungcweti zinganikezwa phakathi kwamahora angu-24 kokubili usuku lokusebenza namaholide.
